Lava rocks buffer to PH7
I've had them in tanks of 5-6.5 pH and never seen them buffer.
This tank has 3 large lava rocks and a tonnes of small pieces as is sitting at 6.2pH and going lower right now and my WCM's just spawned a bunch of babies in it, the rocks aren't buffering anything.
20g platy, , 2 x 10g shrimp, 3 x 20g shrimp, 7.5g shrimp and 1 great dane/mastiff puppy.
